Previous/next post navigation error

– Flushing any caching plugins you might be running, as well as server and/or browser caches. Not just your browser, but any op cache or content network cache as well such as Cloudflare. If your host provider has a “Purge Varnish” option or if you can ask your provider to flush memcache on your server.
– If that does not resolve the issue, keep all plugins deactivated and try switching to the unedited default Theme (Twenty Seventeen) for a moment using the WP dashboard to rule out any theme-specific issue (theme functions can interfere like plugins). If you don’t have access to your admin area, use FTP , or your web-host’s cPanel or whatever file management application your host provides (no Dashboard access required). Navigate to /wp-content/themes/ and switch to the default theme by renaming your current theme’s folder by adding “-old” to the end of the folder name. Alternately, you can remove other themes except the default theme. That will force your site to use it.

The WordPress update did not install the 2017 theme. That’s another issue entirely.

However, I did try 2016 and 2015 and sure enough, post navigation works fine.

Thanks for your reply!

You are welcome ??

I’ve alerted the theme developer.

Thanks ??

Well, now I face a conundrum.

The developer refuses to acknowledge the issue, although it’s clearly related to the Colorlib Sparkling theme. When I change to any of the default WordPress themes, page navigation works correctly.

Any idea where I might look in the theme templates to try to track down the navigation issue myself?

Thanks.
